World crude steel production, 1950-2011
Steel a key driver of the world’s economy
World crude steel production has increased from 851 megatonnes (Mt) in 2001 to 1,518 Mt in 2011 (28.3 Mt in 1900).
The industry directly employs 2 million people worldwide, with a further 2 million contractors and 4 million in supporting industries.
Considering steel’s position as the key product supplier to industries such as automotive, construction, transport, power and machine goods then using a multiplier of 25:1 the steel industry is at the source of employment for more than 50 million people.
World average steel use per capita has steadily increased from 150kg in 2001 to 220kg in 2010.
India, Brazil, Korea and Turkey have all entered the top 10 steel producers list in the last 40 years.

Steel touches every aspect of our lives.
No other material has the same unique
combination of strength, formability
and versatility.

CO2 breakthrough programme
Tackling key programmes for reducing emissions for the industry
Provides forum for sharing BAT,BAP, mitigation techniques and
breakthrough programme
Work scope: focus on co-ordination of programmes ULCOS - Top Gas Recycling, Hisarna, Ulcoreduction, Ulcowin, Ulcolysis
Course 50 Programme, Reduce emissions, Capture CO2 from BF
POSCO – Finex emissions reduction, CCS, H2 steel making
Australian Programme – Biomass use, Heat recovery from Slag
CSC Taiwan – CO2 concentration and separation from flue gas and CCS
AISI – Hydrogen Flash Melting, Molten Oxide Electrolysis
CCS promotion – required technique to make sufficient reduction > 50%

Sustainable steel The amount of energy required to produce a tonne of steel has
been reduced by 50% in the last 30 years.
All steel created as long as 150 years ago can be recycled today and used in new products and applications.
By sector, global steel recovery rates for recycling are estimated at 85% for construction, 85% for automotive, 90% for machinery and 50% for electrical and domestic appliances. Leading to a global weighted average of over 70%.
Steel is the main material used in delivering renewable energy –solar, tidal and wind.
Nowadays, 97% of steel by-products can be re-used.
Water uptake and discharge are close to each other, with any small loss due to evaporation. Water recycled back into rivers and other sources is often cleaner than when extracted.
